[RIGB632] Mary (baptised at Huyton, 20th May
1733), married Thurstan Vouce, see later;

Catherine (baptised at Huyton, 6th July 1735);

Jane (baptised at Huyton, 20th August 1738), mother's name was Mary.

There were two William Rigby's who married a Catherine at Wigan in the 1730's.
Assuming these were not the same William, then the first marriage (to Catherine Gaskill, 2nd October 1732) could relate to this St. Helens family, whilst the
second marriage (to Catherine Winson, 23rd September 1739) could relate to the
family at Billinge who had children 1742-46.

Catherine "wife of William
of Huyton" died at Huyton
(buried at Rainford, 30th May 1789), and
William (a husbandman)
died at Knowsley (buried at Rainford, 20th July 1791).
